I have a 2004 Toyota Camry. I recently replaced the battery and imidiately the car would not run. I took it to the dealer and they did a throttle body clean. The car has not run right since and I am wondering what could be the issue. Clogged fuel injectors, throttle body sensor, timing out, etc.
Anybody have any idea of what I should look at next?
(HP is down, acceleration is weak, fuel mieage is down)

Thank you

None of the stuff you mentioned went bad by replacing the battery. What DID happen is by disconnecting the battery, fuel trim numbers and sensor data were lost from memory. It's not going to run or idle properly until that data is relearned. That's real easy to do on Chryslers by driving the car. Yours should be very similar. Volkswagens require a tow to the dealership and a very expensive repair bill after simply disconnecting the battery.

There will be a set of conditions that have to be met to put some things into memory. For example, Chryslers require coasting for at least seven seconds at highway speed. You might try various things like that.
